FOLDABLE SEAT.

Specification of Letters Patent.

Patented Aug. 14, 191?.

Application filed July 29, 1916. Serial Np. 112,018.

To all whom it may concern.-

Be it known that 1, JAMES MoMILLAN,'a subject of the King of Great Britain, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in Foldable Seats, of which the following is a specification.

My invention relates to improvements in foldable seats, and the object of my improvement is to furnish a seat which may be not only folded up on its supporting standard, but which may be vertically adjusted thereon, and also rocked horizontally into any desired position upon said standard.

This object I have accomplished by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of my improved folding seat, in its extended position, and Fig. 2 is a like view of the same as folded against its supporting standard.

Fig. 3 is a detail view in plan of the upper sleeve-connection for the seat arm.

Fig. 4 is a cross section of the standard, showing the pivotal connection of the lower swing arm thereto.

Similar numerals of reference denote corresponding parts throughout the several views.

The numeral 1 denotes a fixed cylindrical standard, upon which are mounted several sleeves 23, 21, 15 and 17, all longitudinally adjustable thereon and also adjustable rotatably thereabout.

The uppermost sleeve 23 is secured on said standard 1 by a set screw 24, and has a spaced pair of lugs 2 connected by a pintle 3 upon which one end of an arm 4 is pivoted. In the outer part of said arm is a longitudinal slot 8 to receive a bolt provided with a thumb-nut 7 by which the downwardly depending spaced lugs 6 on the bottom of a seat 5 are made longitudinally adjustable along and detachably secured to said arm.

A sleeve 15 is mounted adjustably longitudinally and rotatably on the lower part of said standard and supported upon a sleeve 17 also adjustable on the standard and secured thereto by means of a set screw 20. Said sleeves 15 and 17 have alined lugs 16 and 18 respectively with registering .orifices in which an eyeleted pin 19 is removably seated.

The numeral 12 denotes an arm having bifurcated ends 11 and 13, the upper bifurcations 11 being pivoted on a pintle 9 mounted in a depending lug 10 on the outer end of the said arm 4. The lower end of the arm 12 is curved toward and has its bifurcations 13 pivoted on studs 14 extending from opposite sides of said sleeve 15. Intermediate the sleeves l5 and 23, a stop sleeve or collar 21 is secured adjustably on said standard by means of a set-screw 22.

When the seat 5 is in its extended position as shown in Fig. 1, the sleeve 23 is located a considerable distance above the collar 21 and may be secured on the standard by means of the set-screw 24. If it is required to adjust the seat rotatably with reference to said standard, the pin 19 is lifted from its seat to disengage the sleeve 15 from the supporting collar 17 and the set-screw 24 loosened in the uppermost sleeve 23, and the seat may then be swung hori zontally in either direction.

The seat may be adjusted vertically on the standard by loosening the set-screws 20 and 24 to permit the collar 17 and sleeve 23 to be moved up or down.

To fold the seat toward the standard 1, the set-screw 24 is loosened and the sleeve 23 pushed down as far as the stop-collar 21, which causes the arm 4 and seat 5 with the arm 12 to all swing toward said standard, as shown in Fig. 2. lhe set-screw 24 may then be tightened to hold the parts in closed positions.

My improved device is particularly useful when used and mounted on a standard part of some machine, such as a printing press or other machine, counter or other device. Since the seat may be adjusted rotatably about the supporting body, as well as adjusted vertically thereon, and radially to and from said body, it is peculiarly adapted for the purposes above mentioned. When folded against the standard, it requires but little space, and has no projecting parts liable to be in the way of passers-by, or become entangled with clothing.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In combination, a standard, sleeves adjustably secured thereon for both longitudinal and rotatable adjustment relative thereto, each sleeve having an arm pivoted thereto and the outer ends of the arms pivotally connected to each other, and a seat mounted upon one of said arms.

2. in combination, a cylindrical standard, sleeves adjustahly secured thereon for both longitudinal and rotatable adjustment relative thereto, the uppermost sleeve having a pair of spaced lugs, an arm pivoted between said lugs, a seat, means for securing said seat on said arm, a sleeve loose on said standard below the first-mentioned sleeve, an adjustable supporting collar secured on the 1,2so.sco

standard below and supporting the secondmentioned sleeve means for detachably securing said sleeve and collar together, and an arm having bifurcated ends, one end pivoted on the second-mentioned sleeve, and the other end pivoted to the outer end of the first-mentioned arm.

Signed at Waterloo, Iowa, this 12th day of July, 1916.
